Olderfleet Castle

Olderfleet Castle is a medieval fortress on Curran Point near Larne Harbor, consisting of a four-story tower house with walls measuring one meter thick. The remains include gun loops in the basement and structural features that reflect its role in coastal defense.

The fortress was built during the medieval period and later became significant under royal control in the 16th century. It served a key role in regional defense against external threats during this turbulent era.

The name comes from Ulfrecksfiord, reflecting Norse influence on the region when Vikings named what is now Larne Lough. This heritage appears in how locals speak about their coastline and its seafaring past.

The ruins are located along Coastguard Road near Larne Port and can be reached via a coastal walking path. Parking in the town center provides the best starting point for a walk to the site.

The fort was used for military purposes to counter various sea and land threats due to its strategic location. Its position on Curran Point makes it a vantage point from which visitors can survey the entire Larne Lough and harbor entrance.
